This a 1” Red Devil paint scraper that will function exceptionally well as a binding scraper when properly sharpened.

I bind my guitars with wood but I am sure this scraper will work equally as well with plastic. Most of the time it is necessary to hold the tool at a slight angle and also test to see if you are working with the grain. No Chatter.

I sharpen mine using my 1” belt sander. A file or sanding block will also work. Work the outside edge to a 45 degree angle as straight across as possible.

To prevent gouging the area near the surface to be scraped it is necessary to knock off the corners off the blade.

Last, using a fine diamond file gently remove the burr on the inside of the blade. The resulting cutting edge will be razor sharp. I have found that the working angle of the tools is very effective. This may be the most useful tool in my shop.
